Axpert-Eazy AC Variable Frequency Drive
comes, when the earth current is higher then the value set in B306 for 100
msec. Before reset, check that any output is not shorted with the ground. Set
to 0% to disable the function. The drive will not take second start before 1
minute. 3 starts permitted in 10 minutes. After 3 starts, message will be
displayed "Do not Reset, Contact AMTECH"
If the slave (main control unit) is not responding to the master (Digital
Operation Panel), this fault will occur. It is auto reset type. If the
communication resumes, this will be cleared. In this fault, the AC DRIVE
functioning will be affected only if C405=1.
This fault indicates that the unbalance in output current between any two-
output phases is higher then the set value in B314 for 10 seconds. Set to 0%
to disable the function.
This fault indicates that problem in either driver card or connection between
control and driver card.
This fault occurs when the speed command and speed detection difference is
higher than the set level in B612 for B626 time. This fault is applicable in
closed loop V/f, closed loop vector control and sensor less vector control
mode is selected.
This fault occurs when the detection speed is equal to or higher than the set
level in B611 for 1 second. This fault is applicable in closed loop V/f, closed
loop vector control and sensor less vector control mode is selected.
respective inverter unit.
This fault occurs if heat sink temperature ≥90 ° C or <0° C for 2 seconds of
respective diode unit.
It indicates that one or more current sensor has failed of respective inverter
unit. These faults applicable only for PCA-2013A parallel interface board.
the unbalance, the output current of one or more Inverter Unit exceeds its
rated current for 60 seconds, this fault will come. The rated current of each
Inverter Unit is 600 A for 400 V Series and 387 A (415 A for 7.10C control
version and above) for 500/600 V Series.
This fault occurs if heat sink temperature ≥90 ° C. In cases of multiple Inverter
Units, this fault is for the first Inverter Unit. This fault will also come if one or
more temperature switch is open.
